I believe the answer is true. Hope this helps !!
Answer:
S strain
Explanation:
The Avery experiment demonstrated DNA is the genetic material. It expanded upon the findings made by Griffith.
They used Pneumococcus; Smooth strain which was virulent and the Rough which was not.
Cultures of heat killed smooth strain were prepared after which it was treated with DNases ,RNases and Proteinases to remove DNA, RNA, and proteins respectively. It will then be introduced to living Rough strain.
When treated with RNases only the RNA will be destroyed and transformation will take place leading to colonies of S stains being formed.
Only when treated with DNase did the colonies S strain fail to be formed.
Answer:
Nucleolus
Explanation:
The nucleolus is a compact structure present in the nucleus of fungal cells and all other eukaryotic cells. The nucleolus is not enclosed by a membrane. Nucleolar organizer present in the nucleolus contains the instructions for the synthesis of ribosomal RNAs.
Ribosomal proteins are synthesized in the cytoplasm. The ribosomal proteins are transported from the cytoplasm into the nucleolus. Assembly of ribosomal proteins and ribosomal RNAs to make ribosomal subunits occur inside the nucleolus which then enters cytoplasm to carry out protein synthesis.
Answer:
A
Explanation:
i guessed ona quiz and got it right.
Remember that organisms within a particular environment all adapt in a simultaneous basis depending on the type of environment presented within them. This is part of Charles Darwin's theory of evolution when he observed animals in the Galapagos island.
This survival instinct of the frog can be of disadvantage to it because other animals might be able to recognize their calls due to familiarity of this naturally occurring trait that they do. The frogs can now be more prone to predator attacks within its environment.
